Answer 1

Explicație pas cu pas:

7/8 × 5/2=35/16

3/6 × 5/9 =1/6 ×5/3=5/18(am simplificat in diagonala ,adica

3 si 9 le-am simplificat prin 3)

11/35×14/11 =14/35(am simplifact prin 11 in diagonala )

22/121 ×3/5*20/11=2/121×3/1×4/1 = 24/121( am simplifucat 5 si cu 20 prin 5 si 22 si 11 prin 11)

56/31 ×12/144=56/31 × 1/12=14/31× 1/3 =14/93
